SHEET LIFTING AND COUNTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 500,379, dated June 27,1893.

To all whom it may concern: is rigidly attached to the platform A, and

Beit known that 1, JOHN WV. DARLEY, Jr., a one of the journals either orc is arranged o citizen of the United States, residing at Schenso as togive a vertical play to the rolling rod ectady, in the county ofSchenectady and or wire D.

Thisframe raised a small distance, it will bend on itself,

and the tip d will be under a loop. If new the rotary motion of the wirebe reversed, as will be done by the spring H upon raising the foot fromthe treadle, the tip (Z will return to the initial position, and asecond pressure on the treadle Will raise the corner of the second sheetand so on for the other sheets. The motion of the treadle and thus ofthe rolling Wire may be regulated by the skill of the attendant or byany mechanical means. The rotary motion of the Wire should preferably beabout three quarters of a revolution in each direction. It will be seenthat the sheets will be pushed aside seriat L'm, and if a device forremoving the sheets be attached or a register K for counting the numberof movements in one direction of the rolling Wire, the said sheets maybe removed singly or counted.

\Vhile I have described the device as used upon pads or piles of sheetsof paper; it is equally efiicient in raising the corners of or countinga number of superimposed lengths of thin materials such as calico,linen, and the like.

The device With a register may be depended upon to count Without errorpiles of bank notes, ballots, tickets, &c.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. The combination of a rod or Wire yieldingly mounted in a frame, andhaving a bent arm with an adhesive tip; and means for turning said rodor wire about its axis through any desired arc alternately in eitherdirection, substantially as and for the purposes described.

2. The combination with a suitable platform, of a rolling rod or Wireyieldingly mounted thereon, the said rod or Wire havingabent. arm, andan adhesive tip to said arm; and means for turning said rod or Wireabout its axis through any desired arc, alternately in either direction,substantially as and for the purposes described.

3. Adevice for producing folds in and counting leaves, comprising arolling rod or Wire having a bent arm, an adhesive tip on said arm,mechanism for turning said rod or wire about its own axis through anydesired arc, alternately in either direction; and a counting deviceoperated by said mechanism, substantially as and for the purposesdescribed.

In testimony whereof I alfix my signature in presence of two Witnesses.
